A new study has revealed that Caribbean spiny lobsters have developed behaviours to reduce disease transmission, through creating ‘safe havens’ where they can avoid infected individuals. The study, co-authored by Associate Professor Don Behringer of the University of Florida, showed that the species uses a form of ‘behavioral immunity’ to prevent the spread of the PaV1 virus. […]

Species’ ranges are shifting globally in response to the warming climate and marine organisms that have large ranges are extending their territories further and faster in response, a new study suggests. The new research conducted by the University of Southampton and an international team of scientists has shown that, as expected, species that have large latitudinal ranges are able […]

A brief overview of salmon aquaculture The aquaculture of fish has a long history as a major source of food for humans, and has been practiced worldwide for centuries. Its origins are thought to be in Asia, with China being regarded as the ‘ancestral home of aquaculture’. While aquaculture in general, is still dominated by […]

A team of researchers exploring an active underwater volcano have captured footage of shark species (including a significantly rare species) living within the deep-sea crater. The researchers from the University of Rhode Island were dropping video cameras, bait, and lights – an instrument package called a drop-cam – into the deep ocean off the Solomon Islands as […]

A team of researchers from the University of Southampton have described a new species of Yeti Crab – discovered living in the hydrothermal vent systems of the East Scotia Ridge in the Southern Ocean, Antarctica. Yeti crabs belong to a group of squat lobsters, known as Kiwaidae (named after Kiwa the Polynesian goddess of shellfish), that thrive in […]

Two biology students from the University of Southern Denmark have stumbled upon the mechanism by which starfish remove foreign objects from their bodies –  via squeezing the objects along the length of their body cavities and out through the tips of their arms. The students, Frederik Ekholm Gaardsted Christensen and Trine Bottos Olsen, were originally assigned to tag common starfish (Asterias […]

Climate change could be responsible for leading humpback whales to exhaustion during their annual migration to warmer waters, a new study suggests. Humpback whales (Megaptera novaeangliae) embark on an annual migration along the coast of Western Australia from their foraging grounds in the Antarctic and are likely to face increasing pressure from reduced food availability as a result of […]

The term ‘coral disease’ is generally used to refer to the broad range of ailments exhibited by corals when exposed to biological stressors, including bacteria, fungi and viruses, as well as nonbiological stressors, such as increased sea surface temperatures, ultraviolet radiation and pollutants. Coral disease has increased significantly over the last 10 years, causing widespread mortality among reef-building […]

Phenotypic plasticity refers to the ability of an organism to change its phenotype in response to changes in the environment and it is integral in influencing an organism’s survivability when confronted with habitat variation. Phenotypic plasticity encompasses all types of environmentally induced changes (e.g. morphological, physiological, behavioural, phenological) that may or may not be permanent […]
